FIGURE 7.

Rhizobiales and Rhodobacterales enriched in diseased lesions. The relative abundance of significantly differentiated Rhizobiales and Rhodobacterales amplicon sequence variants (ASVs) per coral sample. On the x-axis, samples are grouped by replicate colonies of four coral species (Stephanocoenia intersepta [SINT], Diploria labyrinthiformis [DLAB], Dichocoenia stokesii [DSTO], and Meandrina meandrites [MMEA]); three sampled tissue types: apparently healthy colony (AH), and unaffected tissue (DU) and lesion tissue (DL) from diseased colonies; and zone (vulnerable, endemic, epidemic). On the y-axis, samples are grouped by bacterial order. The marker size represents the relative abundance of each ASV per sample (scale provided), the shape represents the coral species, and bacterial families are represented by different colors. An asterisk on the ASV name (y-axis) denotes that it was selected as “important” in the random forest analysis.
